in the design and manufacture of advanced mixed-signal Hall-effect
sensor and analog power ICs serving high-growth applications worldwide
within the Automotive Electronics, Office Automation, Industrial
and Portable Electronics markets. We offer cutting-edge technology,
a commitment to quality, and innovative solutions. Our design and
manufacturing teams are ready to work diligently with you to support
your needs.
What Sets Allegro Apart?
Allegro develops total solutions for virtually all power IC and sensing
applications. We provide vertically integrated mixed-signal ICs,
adding more components and greater functionality. Allegro's line
has extensive product breadth and depth, with standard "plug
and play" products.
- The only Hall-effect manufacturer with BiCMOS design capabilities.
- BCD (Bi-polar, CMOS, DMOS) products offer greater efficiency, and control.
Allegro's Mission
Allegro MicroSystems, Inc. will remain a worldwide leading supplier
of analog integrated circuits to the automotive, portable electronics,
office automation and industrial market segments through focused
efforts to
- Provide value to our customers
- Offer technically advanced products
- Achieve growth and profitability
- Challenging the organization to continuously improve, and
- Maintain a positive work environment for our associates
Allegro's Businesses
Allegro is currently organized into two technology-defined groups.
These groups are paving parallel paths of expansion, up-integration,
and diversification by entering or broadening into markets with higher
growth.
The Sensor group produces Hall-effect sensors offering contactless switching for applications such as direction-detection, geartooth, linear, position, and speed sensing for automotive, industrial, consumer, and portable electronics.
The IC group produces power ICs for motor drives, motor control and power interface. Allegro's ICs are used in office automation (particularly printers), industrial, automotive and portable electronics markets.
Allegro's Technology
Allegro is a technology leader, an up-integrated developer of total
solutions for multiple power ICs and sensing applications. The product
success is based on extensive semiconductor expertise and merged
technologies capabilities. Allegro's products are built with
design features that include high-current outputs, very wide operating
temperature range, reversed power supply, and transient protection,
and output short-circuit safety functions.
Mixed-signal processing capabilities allow precision analog circuitry to be used in harsh operating conditions. Allegro has strategically positioned itself in the analog segment, and emphasizes application-specific, market-driven products with high technology content. These include bipolar, CMOS, and DMOS technologies, as well as merged technologies such as BiCMOS (bipolar + silicon-gate CMOS), BCD (bipolar + CMOS + DMOS), and DABIC (digital + analog + BiCMOS). The company can and does combine any two or all three of its product disciplines into a single monolithic chip to deliver powerful system-level solutions. These solutions are sold under Allegro's trademark "ABCD5" (Allegro's BiCMOS, CMOS and DMOS).
Allegro's Products and Solutions
Allegro manufactures Hall-Effect Sensors, Motor Driver ICs, Power Conversion
Devices, Power Interface ICs, and Power Management ICs. Standard
Product Development resources are focused on introduction of the
next generation mixed-signal product solution. The Company focuses
on power output products that add value to overall systems. The end
result are products that offer higher levels of function integration,
lower system stand-by power, and lower output saturation voltages.
SENSORS
Allegro's sensors are based on Hall-effect technology, which allows
contact-less sensing, (devoid of mechanical wear) of either an external
magnet or a ferrous object. Specifically, Hall-effect sensors are used
for contactless switching, position sensing, speed sensing, linear
sensing and gear-tooth sensing. Currently, the auto market is where
the most Allegro sensor applications can be found, applications within
engine, transmission, emissions, suspension, steering, braking, cooling,
doors/windows/seats, airbags, and other systems. Recent strict emission
regulations on boat engines and other small engines will create demand
for like products in these markets.
For Hall-effect sensors, a dilemma can sometimes arise because electronic design engineers are not comfortable with the necessary IC components and mechanical design engineers are not comfortable with the magnets. In these cases, the up-integration of components and sub-assemblies, by Allegro, combining both aspects, is the answer.
POWER ICs
Power IC applications in office automation are led by the motor driver
needs of various printers (inkjet for PCs, vending, P-O-S, etc.),
scanners, projectors, fax machines, copiers and multifunction peripherals.
Driver and controller ICs are also produced by Allegro for fractional horsepower dc, stepper and brushless dc motors in the industrial and automotive markets. BCD technology gives Allegro an advantage in higher power applications and allows expansion in existing markets and associated applications such as large tape drives, automotive blowers, power steering motors, and factory automation.
Power Interface ICs are used in industrial and automotive applications such as relays and solenoids, and LED and VF displays. Display drivers include those used in automotive, medical, scales and signs.
Manufacturing
Allegro understands that investment in manufacturing is critical to
long-term success. The ongoing investment in IC fabrication, packaging,
testing, and handling facilities, both in the US and abroad, ensures
that Allegro is poised to meet the needs of all customers. The Company
is committed to manufacturing integrated circuits with the highest
standards of quality, reliability and service.
Allegro Facts
Allegro, operating under that name for the past decade, is the successor
to Sprague Semiconductor Group, with 40 years combined experience
in the semiconductor industry. With over 2,500 employees worldwide,
Allegro is headquartered in Worcester, MA, where design, manufacturing,
test, marketing and customer service are located in a 250,000 sq.
ft. facility. The Company also has manufacturing plants in New Hampshire,
Pennsylvania, and the Philippines, as well as sales, design and marketing
offices in Scotland, UK, France and Argentina. Sales are balanced
worldwide throughout North and South America, Europe, Japan and Asia-Pacific,
with products sold primarily to OEMs through a strong worldwide sales
channel that includes a direct sales force, manufacturers representatives
and distribution. The Company is ISO 9000 registered
and has received quality awards from leading manufacturers worldwide,
including IECQ manufacturer's approval.
Allegro is a wholly owned subsidiary of Sanken Electric Company, Ltd., a billion dollar company who manufactures semiconductors, discretes, LEDs, and switch mode power supplies, with headquarters in Saitama, Japan. The two companies jointly develop and market leading-edge products in the areas of power management and motion control. This enables both organizations to fully utilize the company's worldwide strengths and resources for the benefit of our customers.
